OBJECTIVETo understand the comorbid characteristics and distribution of combined treatment of Chinese and Western medicine in depressive patients.

METHODThe descriptive statistic method and association rule were used to analyze the data from 19 general hospitals with 3-A level in China.

RESULTAmong the depressive disorder, the most frequent co-morbid physical diseases included hypertension (24.67%), coronary heart disease (16.10%) and cerebral infarction (12.89%), and the proportion of comorbid changes with the increasing age, from 6.51% to 12.55%, 16.33% and 12.47% for hypertension; from 2.79% to 5.69%, 10.17% and 14.22% for coronary heart disease; from 3.72%, 6.27%, 7.70% and 12.25% for cerebral infarction. The use frequency of the antidepressants is 77.18%, and the use frequency of flupentixol & melitracen is 20.95%. The use frequency of Huoxue Huayu Tongluo of traditional Chinese medicine is 59.97%, with that of 27.91% for Ginkgo biloba extract The combined use frequency of Huoxue Huayu Tongluo of TCM and the antidepressants is the highest, especially for the combined use of Shuxuening injection and fluoxetine.

CONCLUSIONThe most frequent comorbid diseases of depression include three kinds of diseases, such as hypertension, coronary heart disease and cerebral infarction, and its proportion gradually increased with the growth of age. The single use frequency of flupentixol & melitracen and G. biloba extract is the highest, while the combined use of Shuxuening injection and fluoxetine is the highest.

Objective To investigate whether insulin secretion and resistance are different in glucose tolerant and intolerant women with normal pre-pregnant body mass index (BMI) during late pregnancy and to find out if there is association between gestational diabetes and insulin resistance syndrome. Methods On the basis of a 4-hour oral glucose tolerance test (OGTT), 32 gestational diabetes mellitus (GDM) patients, 21 gestational impaired glucose tolerant (GIGT) patients, and 50 normal glucose tolerant (NGT) cases were selected from uncomplicated pregnant women. Those had normal pre-pregnant BMI who had a 1-hour 50-g glucose-screening test (≥7 2 mmol/L), performed between 24～28 weeks of gestation. During the OGTT, several indexes of insulin resistance, insulin secretion, lipid metabolism were measured in addition to the standard glucose measurements. Results Glucose area under curve (GAUC), insulin area under curve (IAUC), insulin sensitivity index (ISI) transformed to natural logarithm and triglycerides (TG) are all significantly higher ( P

OBJECTIVETo analyze the influence of retinoic acid (RA) on the undifferentiated state and EB formation abilities of human embryonic stem cells.

METHODSThe biological characteristics of H9 ESCs after RA treatment were characterized by real-time PCR, MTS proliferation assay and immunofluorescence staining. The expression of three germ layers markers, osteogenic differentiation markers and adipogenic differentiation markers in H9-differentiated embryoid bodies (EBs) with RA treatment were quantified by real time PCR.

RESULTSThe proliferation of H9 ESCs in the early logarithmic growth phase was accelerated by RA treatment. In addition, RA induced differentiation of H9 ESC coupled with morphology changes, decreased expression of undifferentiated markers Oct4, Nanog, Sox2 and OCT4 mRNA binding protein Lin28 at mRNA level, and reduced expression of Oct4 at protein level. RA induced formation of cavities in EBs. Real time PCR results showed that the expressions of ectodermal markers: NeuroD1, Noggin; mesodermal markers: Brachyury, Twist and endodermal markers: AFP, GATA-4 were significantly increased (P < 0.05), especially for AFP (P < 0.01), by RA treatment in a dose-dependent manner. In addition, the expression of adipogenic differentiation marker C/EBPalpha was increased while the osteogenic differentiation marker OPN was decreased in EBs after RA treatment for 5 days.

CONCLUSIONSHigh concentrations of RA induced the loss of stemness in H9 ESCs and excessive differentiation in EBs, and damaged the balance between osteogenic and adipogenic differentiation during early EB differentiation, which may be relevant to the congenital malformations.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.

Chronic infection of hepatitis B virus(HBV)presents one of the serious public health challenges worldwide.Current treatment of chronic hepatitis B(CHB)is limited,and is composed of interferon and nucleoside/nucleotide reverse transcriptase inhibitors(NRTI).Interferon is poorly tolerated and is only responsive in a small fraction of CHB patients and NRTIs often face the problem of emergence of drug resistance during long-term treatment.The current treatment of CHB earl be improved in several ways including genotyping mutations associated with drug resistance before treatment to guide the choice of NRTIs and suitable combinations among NRTIs and interferon.It is important to continue research in the identification of novel therapeutic targets in the life cycle of HBV or in the host immune system to stimulate the development of new antiviral agents and immunotherapies.Several antivirai agents targeting HBV entry,cecDNA,capsid formation,viral morphogenesis and virion secretion,as well as two therapeutic vaccines are currently being evaluated in preclinical studies or in clinical trials to assess their anti-HBV efficacy.

Objective To investigate the protective effect of adenosine A1 receptor agonist (2-chloro-N6-cyclopentyladenosine, CCPA) delayed preconditioning on myocardial ischemia reperfu-sion injury and the potential mechanism in rabbits. Methods Thirty New Zealand male white rabbits were randomly assigned to 3 groups:a control group, an I/R group, and a CCPA group. CCPA group was given CCPA 0.1 mg/kg before the myocardial ischemia. Twenty-four hours later I/R group and CCPA group underwent 40 min of coronary occlusion followed reperfusion for 2 h. At the end of the reperfusion, blood samples were taken from the arterial line for determining the plasma level of malondialdhyde and superoxide dismutase activity. The infarct size and area at risk were de-fined by Evans and TIC staining. The heart was harvested and levels of metallothionein (MT) were determined by Western blot, and ultrastructures were observed under the electron microscope. Results The MT level of CCPA group was significantly higher than that of the I/R group (P<0.05). CCPA significantly reduced the infarct size (22.1%±3.8% in the CCPA group) of the left yen-tricular area at risk as compared with the control (41.8%±4.3% in the I/R group,P<0.05). The injury of I/R group was worse than that of the CCPA group under the light microscope. CCPA group had higher superoxide dismutase and lower malondialdhyde than those of the I/R group. Con-clusion CCPA can increase the level of metallothionein during ischemia-reperfusion, which may be part of the molecular mechanism of CCPA delayed preconditioning on cardioprotection.
